In the living room of a Manhattan apartment designed by Steven Gambrel, the custom sofa is upholstered in a de Gournay silk velvet, the 19th-century linen-covered armchair is English, and the nesting tables are early 20th century; the painting is from the 1950s, and the rug is by Stark.

An hotel full of history, it merges the history of the USA with the raise and fall of NYC has an iconic city. The Plaza Hotel has it all!
Let’s go to the design ELLE Decor described pretty well.

A good photograph is a powerful thing: It can transport you instantly from wherever you happen to be right now to, say, a sumptuous suite in the Plaza Hotel. But, having gotten you there, the picture’s potency abates. It cannot describe the way daylight moves through the rooms, for example, or the delightful feeling of spying an undulating expanse of treetops through a sequence of windows.

In the kitchen, the marble-top table is custom made, the linen-covered armchairs are by Lucca Studio, the lantern is from Circa Lighting, and the 1950s painting above the banquette was found in Charleston, South Carolina; the floors are oak, and the strié walls are in Benjamin Moore’s Sterling and Winter Solstice, with trim painted in Stonington Gray.

The patinas Gambrel created for this residence are an homage to the history of the Plaza itself. Designed in French Renaissance–château style, the hotel opened to the public in October 1907, quickly becoming one of New York City’s toniest addresses—and, indeed, one of the most iconic hotels in the world. Alfred Vanderbilt, the railroad heir and celebrated sportsman, was the first guest to sign the register; he was followed, in due time, by Frank Lloyd Wright, Richard Burton and Elizabeth Taylor, the Beatles on their first American tour, Ronald Reagan, and Michael Jackson.
